Hello to all!
After finishing the Tiny 4 Inline from Kelly, it was a time to start a new project.
I have decided for the PeeWee from Bob Shores, it is 4 cylinders in a "V" configuration.
I have purchased the casting kit a couple years ago from Dirk Tollenaar

With the drawings I got a revised version from Steve Hucks. After studying the drawings, I decided to use Steve version as well as following his instructions/guide for machining the Block

I started on the oil pan following the instructions

Hi to all!
Some more work done on the PeeWee. That is the block turn.

I clamped down the block to the table flat on the bottom and just touched the peak of the cylinder banks with skim cut.

The distributor boss was just cleaned up for the scribe line
IMG_20180729_121317584.jpg


The block was then rotated bottom up and a minimum skim cut taken to clean up the bottom.
IMG_20180729_114444530.jpg


The center of the distributor boss was found and transposed to the rear of the block.
The center of the bottom of the block was also found and transposed to the rear of the block and the two points connected.

Faced the bottom to the final dimention

Faced and drilled the the bottom of the center bearing support then installed on the block

Machined the pockets with support in place.

Drilled and tapped the holes for the oil pan

Oil pan installed. Ready for the crankshaf and cam holes

More work done on the block.

Clamped the block on the vise and faced the front of the block leaving 0.2mm for further finishing
IMG_20180802_204913635.jpg


IMG_20180802_211148540.jpg


Turned the block up and machined the rear surface
IMG_20180802_220035103.jpg


Next I clamped the block on a square devise with the front of the block facing up
IMG_20180804_171533249.jpg


I used the parallel on the bottom to asure alingment
IMG_20180804_171547057.jpg


Next I indicated the bottom of the block to get the conter line of the crankshaft
IMG_20180804_171521916.jpg


IMG_20180804_171554611.jpg


Than the crankshaft, idller gear pocket and camshaft holes were drilled. I started with a center drill then used a 8mm drill to start and next a 14.5mm drill bit

More progress on the PeeWee block
After drilling the holes with a 14.5mm drill bit, I used a 12mm end mill to start the idller gear pocket
IMG_20180804_190120501.jpg


Using the boring head, I finished the crankshaft, camshaft holes and idller gear pocket
IMG_20180804_204645965.jpg


IMG_20180804_215201866.jpg


Next I drilled and tapped the holes for the timing cover and water pump
IMG_20180811_172126427.jpg


The block then turned over with the back facing up for the final maching block length. I indicated the hole to find the center in order to drill the water passages holes
IMG_20180812_121817796.jpg


IMG_20180812_163530174.jpg


The following work will be the cylinders holes
I wish to have a better English vocabulary (specially technical) to better explain how I did the maching. I hope the pictures compensate that deficience.

Thanks,

Edi
 
Nice work Edi, this will turn out very nice after your success with your online 4. Great pictures & they clearly show what you intend.

Keep up the great work!

John
 
Hi to all! Thank you Bengt, John and Natale.

I did some more work on the block this weekend, I will post it during this week.
I think I will be able to finish this building faster then the Tiny Inline 4. I have more time available then the previous Project

Tks,

Edi
 
Hello to all there!
I managed to get some more work done on the PeeWee V4

Following the instructions from Steve, I inserted a 13mm (I'm using metric) rod on the crankshaft hole then I found the center of the cylinder bank and marked 6.5mm each side. Using a square I aligned the side of the rod with the sides of the marks to assure vertical alignment.
IMG_20180813_202523123.jpg

Using a pointer, the center of the bank was found
IMG_20180815_205800238.jpg


Indicated rod on the front and the back to assure alignment
IMG_20180813_202630955.jpg


Machined the the top surface to the proper hight and started the holes with a 8mm drill bit
IMG_20180813_213412457.jpg


Next I used a 14.5mm drill bit
IMG_20180813_214429867.jpg


Using the same setup I drilled and taped the head holes
IMG_20180814_210342929.jpg


Finally the boring head was used to finish boring the cylinder holes and counter boring
IMG_20180814_222057985.jpg


The same was done for the other bank
IMG_20180815_224015634.jpg



Next I inverted the block on the vise and I indicated the rod to assure vertical and horizontal alignment
IMG_20180816_204233856.jpg


The distributor boss was machined to the right hight. After finding the center of the rod, the distributor hole was bored and the PVC hole was bored and taped
IMG_20180816_215654241.jpg


That is it for now.
TKS,
Edi
 
Thanks Michael and Bengt for the kind words.
I have managed to get some more progress on the PeeWee.
I cut the water jackets, the Bellhousing adapter and the Bellhousing cast

Indicating the cylinder hole to find the center
IMG_20180819_183951643.jpg


Using a 16mm x 6mm key cutter, the water jackets was cut. I did not use the rotary table, I just moved the X and Y axis (Steve method)
IMG_20180819_201426223.jpg


Here you can see the little pics on the water jackect diameter, because it is not a perfect circle
IMG_20180819_201555653.jpg

As my CNC milling control box is under maintenance I had to use the lathe to machine the Bellhousing adapter
I used a 4 independent jaws juck to hold a 68X57X6mm aluminum blank
IMG_20180818_110329607.jpg


Then it was finished on the milling

Hi to all!
More work done, this time on the Bellhousing
Turning the inside diameter. I have used a four self centering juck
IMG_20180812_192947719.jpg


Here I'm machining a light pass between the tabs to give it more uniformity. I moved the juck by hand back forth using a 3mm end mill on the small grinder adapted on the tool post
IMG_20180812_192638751.jpg


Using a file and sand paper I finished the outside
IMG_20180812_192742661.jpg


Using the same setup the tab holes were drilled
IMG_20180812_202402547.jpg


Using the adaptor plate, Ifixed the bellhousing on it to machine the square on its end
IMG_20180819_171347489.jpg


And finally I gave a touch on the tabs to correct its irregularity. I fixed a 2mm drill bit on the vise and a 6mm on the drill juck. Moving the bellhousing around the tabs were finished
IMG_20180818_202945187.jpg


Here is what I have finished so far
IMG_20180821_075828863.jpg


Next I will start the cylinder heads

Thanks,

Edi

hello,

can the pee wee v4 block work be done on a 7 x 16 lathe with a milling attachment?
 
Hello Atkinson!
I think your equipment can do the job without a problem.
Do you have the castings?

Edi
Edi,

Yes I have the castings. I have been working on some of the small brass parts. So you think I'd be able to do the milling of the block on my lathe with a milling attachment?

Hi Atikinson!

Yes, I think you will be able to machine the block. The only more dificult part is the cylinder bores but, with a little patience you get there.
Go ahead and just start that. You can count on me if you think I could help.

Good luck!

Edi
