Hi everyone
About 2 years ago , before my retirement, i bought plans for construction V4 from Jerry Howell.
I started work the engine block but i suspended it to dedicate myself to the Holt 75 project because i had fallen in love with the characteristic roar of this engine .
Now i resumed Howell V4 which I consider a more challenging project, certainly more complicated.

Hey Foketry.

Just found your V4 build thread and shall be following very closely.

I've given my kids a wishlist for my birthday with the V4 and the V2 drawings on top of the list.

In the mean time I have ordered and printed the Farm Boy drawings and shall start on these.

Plenty of pix of your build please.


Kind Regards,

Coming along nice. Is this a dedicated holding fixture for the piston? I don't quite get the set screw & don't see a split line.

I traded my RF-45 in for a mini Bridgeport clone. I'd like to see your RF-45 CNC conversion one day just for old times sake :)

It is a very simple fixture dedicated to the Howell V4 pistons, there is a screw that locks it.
The phasing is done through a long pin aligned with the X axis of the machine, I use a dial indicator to align the long pin
