New casters

JPG · Post by **JPG** » Tue Mar 20, 2012 3:00 pm

What matters?

The difference in height(∆h) measured vertically from the wheel point contacting the floor and any similar point on the casting(one of those holes will be a good choice) with the casting canted to its normally mounted angle(65° if info above is correct) between the old and the new caster.

Again assuming 65° is correct, the distance along a line passing through the center of both original holes can be calculated by ∆h / Cos 25° == 1.1∆h.

∆h hopefully is the same for all versions of the SS. If not, a template will not always be accurate.

As to the 1 13/16" c-c location between new and old holes, that would imply ∆h is about 1 41/64"(1.642).

I measured my Goldie(sample of one) and 65° is verified! I used 25° above since 65° is floor to leg, and 25° is leg to vertical.

The tubes when secured are resting against surfaces which guarantee leg alignment. Assuming the legs are positioned into the end casting the proper depth, any motion observed will be due to the legs being pulled into proper position.

Does anyone who has put new wheels on their Mark V have old wheels that they need to rid themselves of?

I will agree when Jim verifies the leg height raised above the floor is <0, 1/4", and 1/2" in the three cam positions. Reasonable variation allowed. I define reasonable based upon possible machining tolerances.!

You folks are a tough bunch. I will confirm the 1 and 13/16" between holes measuring center of old hole to center of new hole. As for how far from floor. Sorry guys my arthritis will not allow me to get up again if I lay on the floor to check that out exactly. All of my measurements are from the NEW template and based on prior versus new holes. I will say this once again, The new template is correct and it is designed to be used with the pointy end of the legs in the air. In fact both copies state very clearly "Foot Up" for those of us who are directionally challenged, I translate that to indicate, "Pointy end up!" Rev A is dated 9/11. However my first set of wheels were received after that date and contained older version of instructions. Hey the new version even have easily understood descriptions and great pictures. In fact they show the templates with the pointy end up against the leg and how to center the template and where to mark the centers for the holes. It just occurred to me that these revised instructions by themselves make the wheel set worth the price. Oh yes with the template and machine used as required the new holes are higher on the legs than the old ones. I apologize fellows I am not intelligent enough to clarify this process any further. In fact my brain is sending me the over worked signal. Tis time to return to my shop and add another coat of sealer to my new pen/stylus. Jim

13/16" or 1 13/16"???????

Do the legs clear the floor when in the lower of the two raised positions?

Obviously they recognized the inadequacy of the original instructions.

Sorry to be so persnickety here but lack of same has created much confusion here!

One and 13/16" sorry about my error, I did go back and correct it just now.

Yes the wheels do clear the legs in BOTH lowered positions as they are advertised yet not when in the fully raised position. One more point that I need to make crystal clear here. When I spoke with Jan at Shopsmith she clearly stated that with some of the really old shopsmith models there would be problems with the upgrade. For anyone with a really old (no I do not know how old) a phone call to one of the Shopsmith ladies would be wise prior to ordering. Jim

Ah my question was in itself nebulous.

By raised, I was referring to the LEGS! I was also referring to the LEGS clearing the FLOOR.

I believe you answered in the affirmative(the legs are raised up off the floor when the ss is 'raised' to either cam position, and the legs firmly rest on the floor when the ss is fully lowered).

You have reinforced my concern that the piston bores may have varied over the past half century.

I now am convinced the 'new' instructions are less confusing and less subject to misinterpretation and are 'correct'. I say that only from others comments here, most importantly yours!.

I think it is safe for Ed to order a set!;)

BTW What if he answers instead of the 'ladies'?:eek::D

Okay
As I read and understand this answer I now know

Yes the template when properly used is correct.

Yes the casters when installed using the template do work

And NO you don't have to reengineer SS's design.

Since most after market casters are near SS's price and since they all require engineering/possible modification to work. A wise buyer would order and install the Shopsmith casters.

Thank you Jim for clarifying the caster situation for us!

Now in the future when someone says their Shopsmith with the new casters doesn't work right I can and will automatically assume they aren't installed properly. Most likely because the person did not follow directions.

Again thanks Jim, I will place my order as soon as I figure out everything else I need to order.

How long are the stems on the new Shopsmith casters?

Let us know Ed how it goes installing them. But I don't understand as to WHY ya have to turn the SS upside down to install em.
