MK V Model 500 Table Weight

[reible]

Fence old and new about 2#
Carriage 4#
Table 9#

Does anyone have enough parts to weigh a MK V model 500
table assembly. I would like the weight of the carriage, complete table and fence. Total is fine but individual parts also would be nice.

This is what I have from parts I have.

MK V 520 table, 520 fence and carriage.

Fence 8#
Carriage 7#
Table 26#
Total 41#

10ER table, fence and carriage.

Fence 2#
Carriage 12#
Table with solid tubes 19#
Total 33#


This is inspired from a discussion here on using a MK V table raiser on the 10ER and a question I got from a member on Skip's 10ER group. Some commented here that because the 10ER is cast iron the weight would be a problem. Well, from the above that is not true. I think the MK V 500 is close to the 10ER table weight but I would like to confirm that. The reason is that the question is which version of the MK V table raiser to use, the 500 or the 510/520.

My inclination is that the 500 version is adequate but with out the 500 table assembly weight there is no way to know. Interestingly the 500 table raiser is $3 more than the 510/520 version.

I am going to remove the table raiser from my 520 dedicated drill press and dry fit it to my 10ER dedicated drill press to prove the concept.

Almost 1/2 the ER and more than 1/3 the 5xx.

Here are the weights I could measure quickly this evening. Included are some that you didn't ask for, but I figured I would include them since they were there and somebody might want to know down the road.

Greenie main table #1 (forged and milled rail and table saw insert): 15.2 lbs





Greenie main table #2 (forged and milled rail and table saw insert): 14.8 lbs

Greenie fence and gray fence each 3.4 lbs.



Gray main table with bolted on rail and table saw insert and a plastic bracket that I think is where a saw guard would attach: 12.8 lbs





Greenie aux table with forged and milled rail: 5.4 lbs



Gray aux table with bolted on rail: 7.2 lbs

How and what did you weigh them on?

Where is Dusty on this when we need him

ERLover, I weighed them on our digital bathroom scale. It displays tenths of a pound, but only ever gives a result that is an even number in the tenths place so I think the precision is really one fifth of a pound. And fortunately my wife did not see me carrying the scale out to the garage.

There were changes in the Mark V in 1972 that would affect the lift assist. Some of these older (pre-1972) machines may have been upgraded with a PowerPro headstock and would require the stronger gas cylinder. The lift-assist noted is to support these older machines that have been upgraded.

With almost every machine being upgrade-able and upgrades often being done in different sequences, it does all get complicated covering it with accessory versions.

John,
Maybe a simple "chat" with the MS could get the answer on what the difference is and which one to get. Last fall when they where on sale, I wanted to get one for an ER in DP mode, which I have not installed yet, you said get the one for the 520. I was concerned about the ER weight also. Oh wait, it is here at moms on the FP hearth in the box, let me look.
Packing/shipping list sez, item 556335; Table Lifter (510, 520, MK7).

I am sure the difference is in the the spring cylinder vis-a-vis the different weights. Just as the conventional lift assist is different than the lift assist for the Power Pro. The Power Pro head stock weighs more than the conventional head stock.

I am sure CS will not discuss anything about the 10ER. Interestingly SS has a 10ER manual for sale.

OOPS!! Things get interesting here.

SS is talking about the Power Pro before and after 1972. That page is all over the place.

The only change I can think of that would have a major effect is the diameter of the bench tubes on some of the older machines. Can anyone think of another issue?

Obviously I hadn't thought about an older machine with an upgraded Power Pro head stock. It makes perfect sense now.

Thanks guys for the weights. It looks like the table raiser for the 510/20 is the one that is needed for the 10ER since the 500 table and carriage is lighter than the 10ER.
