Making the rests

[daGrouch]

Hi Guys,

For my first major, for me anyway, undertaking I want to build the rests for my machine. I am going to do a close copy of the Smithy items this time around.

I am hoping someone has some detail pics of a rest, maybe some rough dimensions and a disassembled adjuster. My mental x-ray vision comes up with a few possibilities but I don't want to make things more complicated than they need to be.

The plan so far is to try lost foam casting and aluminum. I worry about resonation and ringing and considered maybe milling pockets and filling with lead (if I can get any - scrap yards won't sell it to me) to act as a damper.

Also, for those that use them, are there any shortcomings or issues with the stock designs I can address during my build?

Any advice is greatly appreciated. I was also thinking of trying to do a YT vid of the project if anyone would be interested.

Thanks,

Try an autobody supply shop -- a professional shop. The really high quality body repairs always used to use lead rather than bondo and it may still be available that way.

I used to pick up old wheel weights from tire shops, and those places that were known as 'service stations'.....that no longer exist.
You might give that a shot.

Indications are wheel weights are no longer made of lead and antimony. In spite of the fact that it weighs far less, they are now being made of steel.

I truly feel that we are being railroaded by some of the restrictions being placed on us, but then that tends to turn to a political discussion, so I'll say no more.

You should be able to get lead from any supplier of blackpowder shooting supplies. Brownell's lists wheel-weight metal for $29.99 for 10 pounds...

Also, if there's an oldfashioned print-shop around, they might sell you either lead or type-metal, which is lead/antimony. (I know, those shops are getting scarce in this era of compuker-printing.)

After you get through chasing around, any plumbing supply store that handles cast iron sewer lines will have lead in brick or bar form, about a dollar a pound. If you have a local scrap /recycle dealer, make a plea there. Wheel weights, rolls of solder, lead chimney flashing, all will appear here. Some solder my be desirable as it shrinks less than lead, and 50-50 solder nearly none at all.

If you do this, just see if your slugs are loose after cast, and if they are, half a tube of slow setting epoxy repair 2-part will flow in and stop that nonsense. The slugs have to be tight in order to cancel vibrations. You will never hear of a lead bell.

Well....how'd I miss that change?
I just looked at my pickup wheels. The weights have 'Fe' cast right in 'em.

Glad I have a couple buckets of the ol' lead weights.

I agree with being railroaded......and will also shut up.....

Good Morning,

Note:One possible source for some real LEAD
would be a small Chrome Plating Job Shop that
might have some drop off's or cut off's of LEAD
ANODES left over from a Maintenance Change Over.
It never hurts to ask.

Try a scuba diving shop. Most dive weight are lead, solid and shot.
