Thanks alot for all the tips and links.

I will mill up some test coupons and give the MEK a go.

I still have all my respirators and gear from doing work inside aircraft fuel tanks and have been needing a reason to pick up an electric hot plate. ::)

Thanks
 
KKB, you might want to steal uh borrow that is, a small stainless steel mixing bowl from the kitchen. The thought of highly flammable liquids in close proximity to open heating elements scares the crap out of me as it is but using a vessel that has seams of questionable integrity in that same situation truly give me the willys. ;D Best of luck and I can not wait to see the final results of your labors.

to get a nice finish on plastics I usualy use No 7 brand auto polish followed by mothers brand plastic polish.
Have gotten good results.

A large pot of boiling water will be more than hot enough to boil a small amout of MEK(or acetone). Please don't have anything with flame or glowing red with heat near these vapors... :eek:

A laboratory style hot plate would be the most suitable for this application I would think. They do not contain exposed resistive heating elements and their temperatures can be exactly controlled. The boiling water idea, though feasible, I would think the steam/water vapor could have a possible negative effect on the final finish.

Thanks for all the tips and info.

I polished the parts like Puputman and a tip from The Shadow (who knows) said to.
Except I used methylene chloride, the same stuff used for bonding.

Set it up like this and heated for almost a minute and then part turned instantly clear. (almost)

Then removed it to fresh air.

Also got a few more parts made;

Cheers!
 

Thanks DIY!

It was teflon but it didn't feel too slick and ended up trying a brass one.

BMyers wait no longer.

Best Regards

Brilliant, elegant, beautiful....at a loss for words here. That's certainly one to be proud of!!! :bow: :bow: :bow:

Bravo! th_wav Very nice, what PSI was it running on when slowed down?

Another great looking engine, another great runner.
You're getting predictable, buddy! :big: :big:

Nice stuff indeed.

Fantastic little engine. The mix of acrylic along with the various metals makes this engine stand out from most others. :bow: :bow: :bow:

I nominate it as an entry for the current engine of the month contest.

cheers

Don

 
Lovely engine Kevin ! :bow:
Well done indeed!
Regards, Arnold
 

Thanks alot fellows!! and thanks alot for the design Paul.


Clearly brilliant.

I laughed out loud on that one :big:

what PSI was it running on when slowed down

I'm not sure BC1, I just have the twist knob regulator at the end of the line. I could hold back the pressure with a finger tho'
(does that make sense or am I getting full tank pressure at a reduced flow ???)


I thought I could squeeze in another small engine before tackling a basement reno. But as you know it is always more work than you think. I was out pretty late trying to finish er up so I could have the rest of the weekend for the house...

Its a little squeaker because I didn't know what some light oil would do to the plastic, esspecially if left on the shelf for extended periods ;)

I'll have to revisit it in the future to do a little better fitting if its going to run off of my small aqua pump.

Glad you enjoyed it,

Kevin.
